HMPROVEMENT IN REVERSIBLE KNOB-LATCHES.

Specification forming part of Letters Patent No. 137,655, dated April 8,1873,' application filed March 2l, 1873. Y l

To all whom it may concern:

Beit known that I, CHARLES S. J ENNINGs, of Meriden, in the county ofNew Haven and State of Connecticut, have invented a new made reversiblefor a right or left hand door by partially withdrawing the bolt from thecase, and particularly to that class in which the bolt and its wholemechanismthat is, the yoke and follower--are drawn forward with thebolt. The object of this invention is tO so hold the follower that itmay be always retained in the same relative position to the yoke, and toinsure the drawing back of the follower, yoke, and bolt into place afterthey have been withdrawn; and the invention consists in constructingthe'follower with a hook upon its rear side combined with a shoe,against which the hub sits, and the said shoe provided with a flange, ofsegmental form, over which the hook On the follower passes, the saidshoe provided with a spring, which will draw the follower and latch-boltback into place and there hold them, as more fully hereinafterdescribed.

A is the follower, perforated for the spindle, as at B, and constructedwith two arms, C C, to act upon the respective arms D of the yoke todraw the latchbolt E, in substantially the usual manner. The `followeris of such thickness as to move freely between the plates door it wouldbe difficult to bring the follower to the position for the insertion ofthe spindie. TO insure retaining in this position, as also toautomatically draw the latch-bolt back into the case, I construct thefollower with a hook, a, upon the rear, and in the rear of the followerI arrange a shoe, F, with an upwardly-projectin g fia-nge, f. This shoelits the sur# face of the follower and forms a seat, as it were, uponwhich to turn. The hook a sets over the fia-nge f, and the flange is ofa seg'-` mental form, so that, in turning'the follower, the hook willtraverse around upon the said flange. This shoe is preferably pivoted atb to the case, and a spring, d, arranged in connection therewith, thetendency of which is to hold the shoe in the position denoted in Fig. 1,and support the follower in proper position. In this position the latchis operated in the usual manner. Toreverse the latch, take hold of thebolt and draw it from the case, as denoted in broken lines, Fig. l. Thisdraws the operative parts forward, as also denoted in broken lines 5 thelatch-bolt may be properly set and left free 5 the spring on the shoewill return the bolt and operative parts into place.

I claim as my invention- 'Ihe follower A, constructed with the hook a,combined with the shoe F, constructed with the segmental flange f, andarranged and operating together substantially as specified.
